NOTE The example below shows a point-to-point configuration type with a remote
connection to two nodes on the fabric. The “Configuration” output line is
“Point-to-point” and there are two different “Primary Remote LIDs”, Primary
Network Addresses” and “Node Descriptions” listed.
Syntax example: itutil -T
Output example:
========================================================================
Topology information for online spigots :
========================================================================
Spigot identifer : 1
Spigot Primary LID : 0xa
Primary Network Address : fe80::ca07:2001
Configuration : Point-to-Point
Primary Remote LID : 0xb
Primary Remote Network Addr : fe80::2:c901:8a0:8a11
Node Description : iblp0091
Primary Remote LID : 0xa
Primary Remote Network Addr : fe80::ca07:2001
Node Description : iblp0088
========================================================================
NOTE This is a partial view of the itutil -T command output pertaining to this step in
the troubleshooting procedure. For more information on the itutil command, see
“Using Itutil” on page 40.
Step 5. Check communication path between nodes.
Run itutil -l.
Description: itutil -l tests the connectivity path between nodes on the fabric. If two nodes are
having a problem communicating, run this command to verify that the path between the two nodes
is functional.
NOTE The example below shows a host successfully connecting to a remote node with the
display message “Linkloop Succeeded.”
Syntax example: itutil -l fe80::2:c901:8a0:8a11 ib0 1
Output example:
Testing connectivity to Network Address 0x<fe80::2:c901:8a0:8a11>
from IA "ib0", spigot id "1"
Linkloop Succeeded.
Step 6. Check adapter transport and performance statistics.
